6. Me and the photographer are allowed to download and upload (on fb for example) your finished artwork of my photo. (We won't use it in a commerical way. And we will give credit to the editor for sure!)

7. Do not use my stock photos as your stock photos!

8. Don't be angry with me if I don't like your artwork with my stock-photo, but tastes differ and everyone has a right to his/her own opinion.

By 300 b.C. Euclides speaks of the non deformability of space. (The space had to be flat.) Later, Rienmann introduced the spaces of variable curvature. (When you move a figure on its surface, space change its shape.) Much later, Einstein speaks again about a flat space, but with curves, because the mass of the stars , curve the space.Then came Quantum Mechanics that says nothing about curves. But strings theory again speaks us of strings, branes and............................ Curiously, more positive and negative space curvature. Now when I see this beautiful picture. ........ We realize that they do not speak of the same curves that we thought now when we look at you.
